/*!
  MFnDynSweptGeometryData provides access to the MDynSweptLine and
  MDynSweptTriangle data for use in a user defined dependency graph node.
  The data is provided as an output from the geoConnector node and
  is primarily used to determine positional information over time.

  If a user written dependency node accepts MFnDynSweptGeometryData, then
  this class is used to extract data that comes from the geoConnector node.
  The MDataHandle::type method will return kDynSweptGeometry when data of
  this type is present. To access it, the MDataHandle::data() method is
  used to get an MObject for the data and this should then be used
  to initialize an instance of MFnDynSweptGeometryData.

  Important note: Users can create the data for connections but
  cannot produce the contents of the data as this is reserved
  for the Maya Dynamics internals.
